What is Add Comments to Video?

Add comments to video without leaving your browser. Upload footage you already have, attach a separate commentary clip, narration take, podcast excerpt, or music track—then stay right here to finish the job. Play a preview, lower or mute the original soundtrack, optionally repeat shorter audio underneath a longer video, then save an MP4 to your device. For the most reliable exports, update to a recent Chrome or Edge. Combined uploads stay around 500 MB total so playback and saving stay steady.

What you can do with this tool

Separate video & audio uploads

Choose your video first. After it finishes loading you’ll see the length and a thumbnail, then attach your narration or music track.

Simple sound controls

Lower the clip’s existing sound or mute it, raise or lower your new track, and switch looping when the new audio ends before the footage does.

Preview before saving

Listen to both tracks together inside the mixer. When everything sounds balanced, export and download.

Roughly a 500 MB upload budget

To keep browsers responsive, uploads add up to about 500 MB altogether. Compress or trim very large originals first if you hit that limit.

No AI-video credits charged here

This merge stays on your machine once files open in the mixer. Separate AI-video credits are only used where you purposely run AI generation elsewhere.

MP4 downloads you can reuse

Save one video file ready for editors, TikTok/Reels uploads, coursework, or other platforms—as long as you follow those platforms’ guidelines.

From prompt to finished video

Jump to the mixer on this page

Use any “go to mixer” button or scroll straight to it. Drag in your foreground video—the tool shows thumbnails and basics once loading completes.

Add your commentary or soundtrack

Import MP3/M4A/WAV or whatever format the picker lists. Narration recordings, VO takes, podcasts, royalty-free cues, or short music beds all work.

Fine-tune the blend

Move the sliders to balance original sound vs. overlay, mute the original soundtrack if needed, toggle looping when your new audio ends early.

Preview your mix

Play back from the mixer and listen for dips, clashes, or overall loudness shifts before hitting export.

Export and save

Start export when you’re satisfied, watch the export progress cues, preview the blended result, then save the downloaded MP4. If exporting fails once, reload and try Chrome/Edge freshly updated.

Who it's for

Voice-over on gameplay or tutorials

Record commentary on another device, then lay it cleanly over muted or lowered game sound before posting shortened clips.

Swap rough dialogue or room tone

Keep the visuals from a hurried shoot but replace scratch audio with clearer narration or narration mixed under lightly.

Trailers promoting audio shows

Layer a looping podcast teaser under simple looped visuals for quick social teaser posts.

Lesson refreshers

Drop fresh narration atop existing screen captures when small script tweaks land moments before publishing.

Why generate on Van Gogh

Visitors often search for narration-friendly workflows. Rather than implying an AI magically narrates for you without audio files, we keep things practical: attach your mastered voice-over or music strip, tweak levels locally, preview, export. That predictable path matches creators who simply need VO over existing footage.

Questions & answers

Is this different from “Add Music to Video”?+

No—the merger is identical. Commentators often arrive from different searches; this page keeps everything inline. Open “Add Music to Video” anytime if you want the longer explanatory article beside the identical tool.

Are AI-video credits deducted here?+

No. Combining files stays inside your browser workspace. Credits only apply where you purposely launch AI-generation flows elsewhere.

Which browsers behave best?+

Recent Chrome or Edge generally export without hassle. Unsupported browsers trigger the usual warning banners—upgrade the browser first if you see them.

Can I silence the footage’s baked-in audio?+

Yes. Flip mute-original so listeners hear only what you uploaded or what you consciously blend underneath.

What if my files are gigantic?+

The combined uploads cap near roughly 500 MB to safeguard browser memory—trim or shrink huge footage before restarting.

What if my narration track is shorter than the video?+

Enable looping—the mixer repeats your selected audio smoothly until the visuals finish, same as Add Music to Video.

Fine-tuning the mix?

Scroll back up to change files, volumes, looping, or preview—then export. Need a fuller walk-through? VisitAdd Music to Video.
